I am thinking of buying a Juki F600. Is this a reliable machine? The nearest dealer is about 90 miles away and I will not be inclined to travel there often. I've read about tension problems (fixable through correct threading?). Are there any others with this machine?

This is a sewing machine question; you posted in the quilting threads so I think you would get more response if posted in the sewing machine section of the board. Have you searched the threads on here? Just do a search and you will find a bunch of posts devoted to the F600. It is becoming very popular. Since you posted in the quilting thread-do you want to quilt on it? Just wondered.
You are fortunate to have a dealer that close-many of the posters I have seen have ordered it online.
